Negative Interest Rates in Review: "Lessons Learned" for the Future

The Paradox of Costs for Deposits

Negative interest rates meant a reversal of classical logic: those who parked money at the national bank had to pay for it. This policy aimed to make the Swiss franc less attractive for international investors and thereby prevent massive appreciation pressure. For the mortgage market, this meant that interest rates for home ownership dropped to historic lows. Banks faced the challenge of securing their margins while savings rates stagnated at zero or—even for very large amounts—slipped into negative territory.

Insights for Property Financing

The years of negative interest rates taught us valuable lessons about market dynamics and risk management, which remain relevant in today's environment.

• The danger of misallocation: Extremely cheap loans led to property prices rising partly detached from economic reality. Buyers got used to an interest rate level that, historically speaking, was an anomaly. The most important lesson here is that the affordability of a property must always be based on a calculated interest rate (usually 5%) to be able to weather periods of normalization without harm.
• Flexibility beats rigidity: During the negative interest rate phase, money market mortgages (now SARON) were often the cheapest option, at times even with rates close to 0%. This taught many owners that taking an active approach to the yield curve can bring enormous savings, provided you have the capacity to sit out fluctuations.

The Psychological Effect of the "Free Mortgage"

A key insight from this period is the psychological component of indebtedness. When money seemingly costs nothing, the threshold for maximum borrowing drops. Many owners dispensed with voluntary repayments, as the return chances on the stock market far exceeded the cost of a mortgage. Today it's clear: those who did not use this period to build reserves now feel the return to positive interest rates much more strongly in their monthly budgets.

Preparation for Future Market Cycles

The history of negative interest rates is a lesson in humility regarding forecasts. Hardly any expert in 2015 predicted that this situation would last for over seven years. For future financing strategies this means: diversification is the best protection. Splitting mortgages into different terms or models (SARON and fixed-rate) prevents being caught unprepared by a sudden regime change in monetary policy—as we saw in 2022.

Is it worth looking back?

Analyzing the negative interest rate phase is essential to understand the current SNB monetary policy and the banks' pricing. It serves as a reminder that market parameters can change quickly and drastically. Those who structure their mortgage today to remain stable even in a volatile environment have learned the most important lesson from recent years: security and liquidity are more valuable in the long term than the short-term hunt for the absolute lowest interest rate.
